Question

Claculate the legth of the circimfrance of a circle with diamiter of 8cm

Answer 1

25.12

Explanation:

8 is the diameter

4 is the radius

3.14 is pi

3.14 x 4 x 2=25.12

Answer 2

Circumference = 2 x pi x r
r = half of d
d = 8
r = 4
Pi = 3.14
2 x 3.14 x 4 = 25.12

Circumference = 25.12
